During the combustion process of 100 L of gasoline, a car releases to the environment, approximately 215 kg of carbon dioxide (CO2). Knowing that one mole is the amount of matter which contains the number of particles equal to Avogadro's constant (6.02x1023 mol-1 ),Determine the number of CO2 molecules that are released during this combustion process.

From a Periodic Table

   carbon weighs ~ 12 gm/mole

   oxygen weighs ~ 16 gm/mole

       so CO2   weighs  44 gm/mole

            214 kg = 214 000 gm

 

214 000 gm  /  44gm / mole = 4863.6 moles

 

4863.6 moles   *    6.02 x 1023  particles/mole    = 2.928 x 1027  particles of CO2
